Do you actually mean "Camille" songs, or just songs where Prince has
speeded up his vocals?...as they're two different things.

The only true "Camille" songs are...

Rebirth Of The Flesh
Housequake
Strange Relationship
Feel U Up
Shockadelica
Good Love
If I Was Your Girlfriend
Rockhard In A Funky Place
U Got The Look
Scarlet Pussy

Of course there are other tracks which feature Prince's voice speeded up
or slowed down, but strictly speaking they're not "Camille" songs. As
Camille was a character/Alter Ego From a very specific time period (87-88).
